Measuring dispenser



Aug. 9, 1938. A. MINTZ MEASURING DISPENSER Filed Aug. so, 1957 INVENTOR WITNESSES lim ATTORNEYS Patented Aug. 9, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to an improved measuring dispenser which may be used for measuring and dispensing cream or other liquids, the object being to provide a construction which is simple and easily actuated at all times.

Another object of the invention is to provide a construction wherein there is presented always a filled dispensing reservoir ready to be discharged.

An additional object, more specifically, is to provide a dispensing measuring device having a pair of reservoirs or compartments and a single valve arranged therebetween for alternately admitting and alternately discharging liquid therefrom.

In the accompanying drawing:

Figure l is a sectional view through Fig. 2 approximately on the line |--l;

Fig. 2 is a sectional view through Fig. 1 approximately on the line 22, the same disclosing an embodiment of the invention;

Fig. 3 is an elevation with certain parts broken away illustrating the valve shown in Fig. 2.

Referring to the accompanying drawing by numerals, l indicates a tank or other source of supply for cream or other liquid which is to be dispensed. In restaurants or elsewhere at the rush hour cream used in coffee is quite often used in larger proportion than desired by reason of the haste of the worker. The dispensing and measuring device embodying the invention is adapted to dispense the exact measured quantity desired upon each actuation so that there will be no waste even if the attendants are in a hurry.

As shown in the accompanying drawing the device is provided with a casing 2 which may be formed with an integral tubular extension 3 screwed into the fitting secured to the reservoir I. The casing 2 as shown in Fig. 2 is provided with an outlet passage 5 in which the valve 6 is fitted. Casing 2 is also provided with enlarged tubular openings 1 and 8 adapted to receive closing caps 9 and it so that the respective compartments ii and 12 will be closed. These openings are provided to permit ready and easy cleaning of the device whenever desired.

The outlet passage 5 tapers slightly to accommodate the taper of the valve 6, which valve is formed with an outlet notch l3 and an outlet passageway Hi. The valve is also provided with an inlet notch or chamber l5 and is illustrated particularly in Fig. 1. Between these chambers there are provided arc-shaped walls l6 and H which are adapted to close the respective openings l8 and I9 which afford communication between the outlet passage 5 and the respective chambers i! and I2. The valve 6 at the upper end is provided with an annular recess 20 adapted to receive one end of the spring 2|, which spring acts on the valve and on the cap 22 for holding the valve in proper place against the walls of the outlet passage. Cap 22 is threaded on to a tubular extension 23 of the casing 2.

The extreme upper end of valve 6 is provided with a squared part 24 which is adapted to receive the squared socket 25 of handle 26. A small set screw 2l' acts to lock the handle 26 on the squared part 24. A vent passageway 28 is provided in the upper part of valve ,6, said vent passageway merging into the notch l3. A second vent passageway 29 is formed in handle 26 so that when the parts are turned to the position shown in Fig. 2 ample air may enter to permit the liquid to flow from the chamber l2 out through the passageway l4. While the liquid is flowing out of the chamber l2 liquid from the tubular member 3 will be passing in through the opening [5 into chamber ll so that by the time that chamber i2 is empty chamber H is filled. If a second batch of liquid is desired, handle 26 is shifted over to the other extreme position as indicated in dotted lines in Fig. 1 whereby the notch IE will register with the opening l8 and the notch I3 will register with the opening I 9. This will allow the chamber or compartment I I to discharge and the other chamber tobe filled from liquid passing through the stem or tubular member 3.

It will be seen that there is always provided a a reserve measured quantity of liquid in the device and that it is only necessary to move the handle 26 back and forth tosecure successive measured quantities of liquid. This movement is preferably a ninety degree movement although a greater or less movement might be provided if desired.

I claim:

A measuring liquid dispenser comprising a onepiece casing having three closely adjacent, axially parallel compartments, the intervening walls of which have openings centering in the same horizontal plane to provide common communication, a fluid inlet directed into the central compartment, a valve rotatably mounted in the central compartment formed with oppositely facing notches of heights substantially equal to the height of said compartments and having an outlet passageway at the bottom merging into one of said notches, and a hand actuated member connected to said valve for rocking the same so that at one time the notch in communication with said outlet passageway will be in communication with one of said compartments and when in a second position will be in communication with the other compartment.
